Capacitor Based Metamaterial Absorber for Obtaining Wideband Absorptivity
This work proposes the establishment of capacitive effect to a square shaped SRR to obtain ultra wideband absorptivity. The proposed metamaterial absorber is working in complete X-band (8-12GHz) frequency. Initially the structure was designed by a square shaped ring resonator placed inside another ring with open slot. The dual band absorbance at 9.4 GHz and 13.4 GHz with absorptivity 99.88% and 97.26% respectively is achieved in the initial design. Then, to accomplish wideband absorbance, a lumped component (Capacitance) is introduced, where it capped the complete X-band of absorption above 90%. The FWHM bandwidth of the wideband metamaterial absorber is found to be 6.4 GHz. The suggested absorber shows a good absorptivity for both TE and TM modes.
